:60, :30, and :15 second versions are recommended for commercial use

Any fade must end within the time duration (e.g. a :30 second version should not have the final hit be on :30 and fade until :34. That would not work for a :30 commercial).

Narrative versions are recommended for commercial use. This is a version that has no lead melodic vocals or instruments.

Other instrumental versions you believe could be useful are recommended. e.g. drum and bass version, percussion and sfx version, or no drums version

Vocalese versions are recommended. This is a version that has non-lyrical vocals (e.g. heys, ahhs, oohs).

Instrumental versions are recommended. There must not be any vocals in this version.
